The Navy wants to expand the 5,183-acre range because military officials say it’s too small to conduct training for combat pilots. They say an expanded range would allow pilots to conduct realistic tactics, techniques and procedures they’re unable to do now.

The Marine Corps says it needs the additional room to support the training necessary to use modernized weapons systems.

The range is used by six F/A-18 Hornet Squadrons stationed at Marine Corps Air Station Beaufort, S.C.

During the comment period, which will end April 20, the public can learn more about four possible options for expansion.
